This video takes a deeper look at the concept of protocols, following the videos on network topologies. TCP/IP for routing and error checking primarily on wide area networks is considered, together with HTTP and HTTPS as protocols for the transfer of web pages. FTP as a protocol for the transfer of files, and the popular email protocols are also outlined: POP, IMAP and SMTP.
